ABSTRACT
Serratus anterior (7.25 g; Fig. 5) • Attachments: From ribs to medial side of scapula, being well separated from
levator scapulae. • Usual innervation: Long thoracic nerve (Deniker 1885, Eisler 1890, Sommer
1907, Preuschoft 1965), from C5 and C6 according to Hepburn (1892). • Notes: In gorillas, the serratus anterior might originate from ribs 1-13 (e.g.,
specimens of Hepburn 1892, Raven 1950 and juvenile specimen of Deniker 1885), ribs 1-12 (e.g., specimen of Stewart 1936 and fetal specimen of Deniker 1885), ribs 1-11 (e.g., specimens of Duvernoy 1855-1856, Bischoff 1880), or ribs 1-10 (e.g., specimen of Macalister 1873).
